Pressure Measurements Manufacturer,Supplier and Exporter in India
Product Code : EL-MLE-13256
Jlab Export is a leading Pressure Measurements Manufacturer,and suppliers in India
Pressure Measurements (code EL-MLE-13256) is a pressure measurement bench, model JL111/04, on which students investigate and compare inclined and U-tube manometers with Bourdon-type vacuum and pressure gauges. A separate Bourdon gauge with dead-weight calibration apparatus lets the Bourdon tube mechanism be seen clearly. The two-unit pressure bench is manufactured by JLab in Ambala, India.

Comparing Manometer and Bourdon Readings
The syringe assembly raises or lowers the pressure for each set of readings. In the vertical U-tube the pressure difference is Δp = ρgh, from the difference in liquid levels. The inclined limb spreads the same vertical height over a longer reading length L, with h = L sin θ, which makes small pressures easier to read. The Bourdon gauges work differently: a curved tube of oval section tends to straighten as the pressure inside it rises, and a linkage turns that movement into pointer travel, while the vacuum gauge reads pressures below atmospheric.
Calibrating a Bourdon Gauge With Dead Weights
On the calibration unit, known weights on a piston of known area produce a pressure p = W/A. Loading the weights in steps and noting the gauge reading at each step gives a calibration curve and the gauge error across its scale, while the visible mechanism shows how the tube, linkage and pointer respond.
